Adding e-start to 450F?

OKRedline

My best friend has an '09 YZF450. He's mentioned that he is liking the idea of electric start more and more. He keeps saying he wants to find a way to add electric start to his bike.
Can you add e-start to this bike? Would it even be worth it?

Personally I think my friend is just a puss and needs to suck it up. Not that I have anything against e-start, but if you didn't want to screw with a kick start you shouldn't have bought a kick start bike.
